I know it's a crab but what kind?

Well that little crab that came along with my last frag pack and found it's way into my tank, the one I thought was dead, NOT! Anyone tell me what kind it is?

Update: I've observed this little guy eating the purple stuff on that rock. His claws are white tipped and he has red eyes. I've looked at pic's of a Gorilla Crab and the body looks similar but his claws are not black. Do they turn black as they get older.

Doesn't matter, general rule is if they are hairy, or claws are tipped in a different color they are probably bad. I have no idea what he is, but if you get the chance to catch him and separate him until ID, I WOULD!!!
